Precipitation Hardening (PH) Stainless Steel

PH alloys are similar to other stainless steel and nickel-based alloys, with one major exception: They contain small additions of copper, aluminum, phosphorus, or titanium. After a part made of a PH alloy has been formed, it is given an age-hardening treatment in which these elements precipitate as hard intermetallic compounds that significantly increase hardness and strength.

Duplex Grades Stainless Steel

This grade of stainless steels is called “duplex” because these alloys have a two-phase microstructure which consists of grains of ferritic and austenitic stainless steel.
